This report describes the design, fabrication and test of components subsystems and organic Rankine cycle Power Plant. Design point net output power is 1.5 KW at 28 V.D.C. Power is produced by combustion of an air/fuel mixture and transferring the thermal energy to CP-25, the working fluid, which is expanded through a turbine. The turbine is part of a turbo-alternator which also powers internal accessory components. Specific design criteria involves precise quality of power, weight, volume, efficiency, life and noise limitations, severe environment and shock, and multi-fuel operating requirements. The set is portable, self-contained except for fuel supply and is intended to operate as a silent power plant.
